Title: Bathtub
Inventor: MORISHIMA NORIHITO
IPC: A47K3/02
Filed: 1995-04-26
Abstract: PURPOSE: To prevent defective molding defects, such as air pocket and cracking, by making a totally sloped face for the portion extending from an outer edge of a projection in a lower external wall, the projection corresponding to fittings attachment part, to a peripheral external wall face. CONSTITUTION: A bathtub is provided with a drain port 11 and a fitting attachment part 13 around the drain port 11, where a lower internal wall face 12 is depressed stepwise to form the fitting attachment part 13. A lower external wall face 14 is provided with a projection 15 at a position which corresponds to the fitting attachment part 13, and the projection 15 is provided with a sloped face 16 extending from the outer edge 15a to the adjacent lower external wall face 14.

Title: Signal line filter
Inventor: TOKANE HIKOHIRO
IPC: H04B15/02
Filed: 1990-04-18
Abstract: PURPOSE:To always bring a ferrite core into close contact with a flat signal cable whose thickness size is different and to increase a noise absorption amount by installing a clamp by which the signal cabe which has been inserted into and passed through the U-shaped inside of a U-shaped ferrite core is fitted and compression-bonded to a sheetlike ferrite core. CONSTITUTION:A signal line filter 1 is constituted of the following: a U-shaped ferrite core 3 as a magnetic core; a sheetlike ferrite core 5 which can be fitted to the U-shaped inside of the ferrite core 3; and a clamp 4. A flat signal cable 2 is inserted into the U-shaped ferrite core 3; the sheetlike ferrite core 5 is fitted to the U-shaped ferrite core 3 so as to cover the cable; these three are compression-bonded and fixed by using the clamp 4. Consequently, the close contact property of the ferrite core as the magnetic core with the signal cable 2 can be kept always good even in the case of the flat signal cable 2 whose thickness size is different. Since the magnetic core is brought into close contact with the signal cable, a magnetic resistance can be made small and a filter effect is enhanced.

Filed: 1990-04-17
Abstract: PURPOSE:To make it discriminable that from which device a status is transmitted to a bus when the status is monitored by making each device connected to the same bus to add an identifier(ID) number peculiar to each device to the status of each device when each device transmits the status. CONSTITUTION:A value peculiar to a device connected to a token passing bus is set in the device as initialization from an ID number setting switch 24. When the device receives a BOM (a controlling word indicating the commencement of data) thereafter, a driver/receiver 20 sends the BOM to a reception circuit 21. When the device receives an EOM (a controlling word indicating the end of data), the receiver 20 sends the EOM to the circuit 21. The circuit 21 informs a control circuit 25 of the received EOM and a code indicating whether or not a status response is required. The control circuit 25 transmits the content of the ID number setting switch 24 and received results to a received message to a bus as a status when the code indicates that a status response is required.

Title: Controller of inverter
Inventor: IWASAKI MASAHIKO
IPC: H02P27/08
Filed: 1984-05-21
Abstract: PURPOSE:To eliminate the insufficient torque at a heavy load time by always detecting an input current, and always correcting the primary resistance drop of an induction motor due to an increase in a current, thereby preventing the exciting magnetic flux of the motor at the heavy load time. CONSTITUTION:A current detector 10 detects the DC current of a DC bus, compares with the current value from a current value setter 11 at no load time, and detects the increase of the current due to the load. Then, a voltage proportional to the current increase from a correcting voltage output circuit 12 is output, the corrected voltage is added to a voltage output from a voltage frequency ratio circuit 8, and input together with a frequency command from a cushion circuit 7 to a PWM generator 9. Thus, even if a current increases due to a heavy load, the exciting voltage E is held constantly. Thus, the insufficient torque due to the reduction in the exciting magnetic flux can be eliminated at a heavy load time.

Title: Cutting insert
Inventor: KATAOKA HIDEAKI
IPC: B23B27/22
Filed: 1995-04-26
Abstract: PURPOSE: To smoothly discharge chips in a spiral spring shape by forming a pair of left and right projections which are positioned so as to respectively separate in order from the front end cutting edge rim and the side part cutting edge rim and become higher in order. CONSTITUTION: At grooving work time, first of all, chops cut by the front end cutting edge rim 3 contact in order with almost semispherical first projection 6, second projection 7 and third projection 8, and the chips are smoothly discharged in a spiral spring shape. Since a diameter of a spiral spring to be formed does not become too small, the chips do not clog in a groove at grooving work time. Since the chips contact with a projecting spherical surface, the contact area is very small, and since cutting resistance is small, an unintentional movement is not caused on a work surface. Since a cross section of the chips becomes a curved shape narrowed down inside, they do not twine around a holder.

Filed: 1987-04-28
Abstract: PURPOSE:To realize a heat exchanger capable of enhancing a cooling effect and capable of suppressing a pressure loss and dew condensation by a method wherein a cooling plate is installed over a considerably wide area along a laser gas flow and a pipe for coolant use is installed at the cooling plate in such a way that the pipe closely adheres to the cooling plate. CONSTITUTION:A laser gas is made to flow by using a blower 3. Because this laser gas flow flows smoothly along a guide 5 and a cooling plate 11 inside a laser housing 1 and flows along the cooling plate 11 which is cooled efficiently by means of a pipe 12 for coolant use, it is cooled efficiently. In addition, because an obstacle such as the pipe for coolant use or the like does not exist in a flow route of the laser gas flow, it is possible to increase a flow rate. Water or a coolant whose cooling effect is bigger than water flows and circulates through the pipe for coolant use or is filled in the pipe. The coolant inside the pipe for coolant use is discharged from this laser oscillator and its heat is radiated.
